Colorless or red roses monoclinic system crystal. The relative density of 1.82, melting point 25.8 ℃, boiling point of 129.4 ° C Soluble in water, slightly soluble in alcohol. Industrial is usually a manganese nitrate solution containing 61% and 70%.
Manganese(II) nitrate is an inorganic compound with formula Mn(NO3)2. Each formula unit is composed of one Mn2+ cation and two NO3- anions and varying amounts of water. Most common is the tetrahydrate Mn(NO3)2·4H2O, but mono- and hexahydrates are also known as well as the anhydrous compound. Some of these compounds are useful precursors to the oxides of manganese.
Manganese(II) nitrate can be prepared by dissolving manganese(II) carbonate in dilute nitric acid:
MnCO3 + 2 HNO3 → Mn(NO3)2 + H2O + CO2
It can also be prepared from MnO2 and nitrogen dioxide.
